Large-cage occupation and quantum dynamics of hydrogen molecules in sII clathrate hydrates
Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri
Hydrogen clathrate hydrates are ice-like crystalline substances in which hydrogen molecules are trapped inside polyhedral cages formed by the water molecules. Small cages can host only a single H-2 molecule, while each large cage can be occupied by up to f ...
Aip Publishing2024The Structural Dispersity of Oligoethylene Glycol-Containing Polymer Brushes Determines Their Interfacial Properties
Harm-Anton Klok, Alberto Ongaro, Irene Filipucci
Ought to their bioinert properties and facile synthesis, poly[(oligoethylene glycol)methacrylate]s (POEGMAs) have been raised as attractive alternatives to poly(ethylene glycols) (PEGs) in an array of (bio)material applications, especially when they are ap ...
Amer Chemical Soc2024Advances in hydration and thermodynamics of cementitious systems
Karen Scrivener, Patrick Juilland, Aslam Kunhi Mohamed, Fabien Jacques Michel Georget, Thomas Matschei
Optimising the hydration of cementitious materials is crucial to leverage their full potential and avoid wasting resources, embodied energy and CO2. Understanding the fundamental mechanisms is key to reach these objectives. In this paper, we review progres ...
Oxford2023Hydro-mechanichal characterisation of bentonite/steel interfaces
Alessio Ferrari, Eleni Stavropoulou, Fabiana Sannasardo
The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction co ...
2023Microstructural developments of limestone calcined clay cement (LC3) pastes after long-term (3 years) hydration
Karen Scrivener, Franco Alberto Zunino Sommariva
LC3 is one of the most promising alternatives for a high-performance blended cement with a significantly lower clinker content and with potential for worldwide adoption. For this reason, understanding its long-term performance is relevant to ensure service ...
PERGAMON-ELSEVIER SCIENCE LTD2022The influence of sulfate addition on hydration kinetics and C-S-H morphology of C3S and C3S/C(3)A systems
Karen Scrivener, Franco Alberto Zunino Sommariva
A comprehensive understanding of hydration kinetics, sulfate requirement and phase assemblage of Portland cement is crucial for further optimization of early-age performance, especially when part of cement is replaced by mineral additions in blended cement ...
PERGAMON-ELSEVIER SCIENCE LTD2022Alite-ye'elimite clinker: Hydration kinetics, products and microstructure
Karen Scrivener, Ruben Anton Snellings, Xuerun Li
This paper presents the hydration kinetics, products and microstructure of an alite-ye'elimite clinker containing 4 wt% of ye'elimite to boost the early strength development. Isothermal calorimetry, X-ray diffraction, backscattered scanning electron micros ...
ELSEVIER SCI LTD2021Strength-promoting mechanism of alkanolamines on limestone-calcined clay cement and the role of sulfate
Karen Scrivener, François Henri Avet, Xuerun Li, Wilasinee Hanpongpun, Hong Huang
This paper reports the strength-promoting mechanism of alkanolamines on limestone-calcined clay cement (LC3). The hydration kinetics, phase formation and microstructure of LC3 with triethanolamine (TEA) or triisopropanolamine (TIPA) were investigated. TEA ...
PERGAMON-ELSEVIER SCIENCE LTD2021Factors affecting the reactivity of slag at early and late ages
Karen Scrivener, Yosra Briki, Mohsen Ben Haha
This study investigates the difference between the reactivity of slag in NaOH solution (w/s = 100) and in cement paste (w/b = 0.4). The reactivity of slag is much higher in NaOH solution than in cement paste. When the NaOH solution is saturated with portla ...
PERGAMON-ELSEVIER SCIENCE LTD2021Microbial-induced carbonate precipitation applicability with the methane hydrate-bearing layer microbe
Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...
